Application filed January 18, 1915. Serial No. 2,885.

ToaZZ whom it may concern Be it known that I, GRAHAM D. Tyson, a citizen of the United States of America, and a resident of Salem v in the county of Roanoke and State of Virginia, have invented certain new and useful Improvements in Cutting Mechanism for Cigarette- Machines, of which the following is a specification.

This invention relates. to improvements in cutting mechanism for clgarette machines and the ob ect of the invention is to proing part hereof: Figure 1 is a side elevation of the end of a cigarette machine'having my cutting mechanism secured thereto; Fig. 2

is a side elevationviewed from the opposite side to that shown-in Fig.1; 3 is an end elevation; Fig.4r is a top plan view;

Fig. 5 is a side elevation of the ledger plate and its parts in their normal positions; Fig.

6 is a perspective view of the same parts when the ledger plate has been shoved clownwvard by the cutter finding an obstruction in the cigarette rod; Figs. 7 and 8 are diagrammatic views of a modified form of the eccentrically arranged shafts; Fig. 9is' a given to the cutter.

diagrammatic view of still another form of the eccentrically arranged shafts; Fig. 10 is a diagrammatic view showingthe movement Referring now to ings by numerals 1 designates the end of the main frame or tabled a cigarette machine. the machine proper not beingjillustrat ed and 2 designates the main drive shaft which not only is intended to operate all the parts of the cigarette forming machine, but operates the cutting mechanism invented by me and illustrated in the drawings. 'This main drive shaft 2 is supported in suitable the details of the'drawbearings and through the worm gearing 4' and 5 is arranged to drive a gear 6 upon a supplemental shaft 7. This gear 6 meshes with and drives an idler 8 journaled upon a shaft 10 supported by bearings in an arm 12 'adjustably held in position by means of a bolt 14 (see Fig. 1). This idler gear 8 drives the main gear 16 of my cutting mech anism and thisgear 16 isadapted to drive all the other gears to operate the cutting mechanism. The main frame or table 1 has a supplemental table 18 adjustably secured thereto. This table may be held and adjusted in any desired way, but in my drawings I have disclosed the table as having a downwardly projecting standard 20 which fits within a vertical opening in the main frame or table 1 so that the table 18 may be adjusted vertically with respect to the table or frame 1. In order to provide for this adjustment the standard 20 has ,a screwthreaded aperture within which fits an adjusting screw 22 to which is secured a worm gear 24: operated by a shaft 26 on the end of whichis an adjusting bolt head 28. It follows from this construction that when the shaft 26 is rotated by a wrench being applied to the head' 28, the shaft 22 may be. rotated for the purposeof raising or lower ing the table 18 with respect to thev table 1.

The platform or table 18 is designed to support all the'frame work and bearingsfor the different gears and shafts. To this platform or table 18 is secured, as by bolting or otherwise, two frames 30 and 32, the frame 30 being provided with three bearings 34, 35 and 36, while the frame 32 is provided with three bearings 37, 38 and 39. As will be seen from an inspection of Fig. 4-,- the bearings on the frame 30 are out of alinement with the bearings on the frame 32, for a purpose to be hereinafter described. The bearings 34, 35 and 36 contain shafts 10, 11 and 4 2, the shafts 10 and 42 having gear wheels thereupon of equal size desig nated by the numerals 43 and 44, both 'of which mesh with the main gearlfihereinbefore referred to (see Fig. 1). It follows from this construction that the shafts 40 and 42 will be driven at uniform speed. The shaft 11. has fiXedto it a gear 15 which also meshes with and is driven from the gear 16. "The bearings 37 and 39 contain shafts 46 and 47 which, as will be'observed from Fig; 4,-are out vof alinement with the shafts with the shaft 41.

40 and 42. Likewise the bearing 38fcontains a shaft 18 which is. out of alinement The shafts 4:0 and 46 have'secured to their innerends cranks 49 and 50 which in the-embodiment illustrated are cross-heads and these are connected by a link 51 ,"one end of which is pivotally connected to one cross-head 49 and the other end pivotally connected to the other crosshead 50. The shafts 42 and 47 have simi- V lar cranks or cross-heads 52 and 5.3 connected by a link 54 while the central shafts ll and-48 also havesimilar cranks or crossheads 56 and 57 connected by a link 58. The outer ends of the shafts 4 :6 and 47 are provided with a pair of cranks 60 and 61 Whose crank pins 62 and 63 (see Fig. 2 enter bearings64 and 65in a horizontally reciprocable frame 66. This frame 66 has integrally secured thereto a pair of horizontal "bearings 68 and 69 in which is journaled a sleeve 70 which is capable of rotation as well as longitudinal reciprocation in said bearings 68 and 69. Within the sleeve 70 is 'journaled the cutter shaft 71 to one end of which is secured a rotary cutter 72 and to thekopposite end: of which is secured a grooved pulley 7 3. iifgrooved pulley with afsimilar pulley 74 supported upon a countershaft 7 5 journaled A belt connects this in abearing 76 projecting upwardly from the bearing 34 .hereinbefore described. Upon the same shaft .7 5 which carries the pulley v74 is supported a third pulley 78 whichis'jconnected by a belt 7 9 witha drive 3 'pulle'v 80 fixed to the main or drive shaft" ;2; V The result of "thismechanism is that l the-cutter shaft 71 and;its rotary cutter 72- fi'si rotated at a high speed through the belts andpulleys, during'the time that the shaft 71 anditscutter 72 arem0ved back and. forth in the bearings-68yand 69 in the man 'ner'hereinafter describedf To. the outer end Qof'theshaft 48fis; secured a crank disk 81 whose crankpin 82 is connected by 'means of a link' 83 with a head84 clamped to the sleeve '70 already referred to as inclosing the cutter. shaft 71.1 The result of this construction is; that when the shaft 48and its crank disk ,81 are rotated, the sleeve 70 and its shaft 71 will be given a longitudinal movement; within the bearings 68, and 69 above referred to. V 1 i .From the foregoing, it will beseen that the-cranks 60 and 61 impart a circular movement to every part of the horizontal frame 66 which in effect causes an up and down 1 60 movement, fand the crank disk.81- through the link 83-imparts a reciprocating move- 1 ment to thesleeve 70 and its shaft 71 in'the {bearings carried by said frame so that the cutter carriedby the shaft 71 has both an up and down movement and af movement longitudinal of itscutter shaft '71, these movements taking place simultaneously.

These movements will be more fully re- 'ferred to'hereinafter. Y i

The rotary cutter 72 is so placed that its,

cutting edge will rotate against .a ledger plate 90, see Figs. 1 and 4. This ledger plate has the usual bell shaped mouth 92 for receiving the cigarette rod as it is continugl. ously formed by the cigaretteforming ma chine. It is theipur'pose of my inventionto r have this ledger plate and. its bell shaped mouth 92, together with the rotary cutter 72, travel, in one direction, at'as nearly the same speed as possible with the uniform speed of the continuously formed cigarette 7 rod. Therefore the ledger plate andits forth upon the frame simultaneously with the rotary cutter 72.. To accomplish this purpose I support the ledger plate upon a bell shaped mouth 92 must move' back and bracket 94 which is pivotally; supported upon a rod 96 longitudinallyslidable in bearings 97- 98.formed*on the upp ends of brackets 99 and 100 boltedto the mainframe, see Fig. 2.. e V

The bracket 94. which has been" described as pivotally supported on the rod 96 moves with the rod 96 as the latter is moved 'lon gitudinally in its bearings 97 and 98 To give the rod 96 such a'longitudinalmovement, I secureto said rod a clamp. 101 pro-f vided with an upwardly projecting'arm 102 which is connectedfltoja'downwardly projecting arm 103 --integrally secured to the aforesaid sleevefififl by means" of; a clamp the back and I forth movement. of the clamp 101fwith its sleeve/Z0 The result of. this construction is'. that when, the frame '66 is, given movement bythe cranks v60and 61 the '7 V slot-105 permits thearmf 103 tomove up and:

down withjresp'ect to; the arm:102,"and',as

the sleeve 7 70 is given a longitudinal move ment inits beari'ngs 68 and69, similar movementzis giventothe clamp 104 which therefore compels: the arms 102 and- 1O3to have a similar'backfand forthmovement;

This back andforthr movement of the arms! -102 and 103 of courseis imparted to the rod 96, for the arm 102 is secured to therodi 96 by means of the clamp 101; thereforeithe' rod 96has similarlongitudinal movement tothe longitudinal movement of the sleeve 7 0 and as the ledger plate. 90 with its bell;

shaped-mouth 92 issupportedby the'rod 96, Q saidledger plate and its bell shaped mouth, V i ar'e' comp'elled to travel back and forthwith the rod 96 simultaneously with the back'and" forth;- travel ofthe sleeve 70 the cutter Shaft; isol- 71 and the cutter 72. In order to prevent any serious injury should any wire or other foreign substance be accidentally formed into thecigarette-rod, I have constructed the ledger plate 94 so that it may give under undue strain. For this reason the bracket 94 is pivotally supported on the rod the two arms 110 and 114 being connected by a coil spring 115. This spring 115 normally holds the parts in the position shown in Fig.

, 5, but should there be any foreign substance within the cigarette rod, as for example a piece of wire, the moment the rotary cutter strikes said foreign substance in the act of cutting, the whole ledger plate will be forced down against the tension of the spring115, the arm 110 moving on the rod 96 thus separating the two arms 110 and 114 as indicated inFig. 6.. s As soon asthe knife recedes as it is moved upwardly by the further operation of the machine, the spring 115 will draw the two arms 110 and 114 together and return the parts to normal position as shown in Fig. 5.

' I have .hereinbefore referred to the fact that the shafts 40, 41 and 42 are eccentrically connected to the'shafts 46, 47 and 48 by means of the pivoted links 51, 54-and' 58. The result of this peculiar connection is that the gear wheels 43 and 44 inpart an irregular movement to the cranks'60 and 61 carried by the eccentrically arranged'shafts 46 and 47, causingthe cranks to have a slower or retarded movement at one pa'rt of their',.rotation and an accelerated or faster movement at another partof their rotation.

. The retarded movement is during the time the cranks are moving the frame 66 upwardly and the accelerated movement is while the cranks are causing said frame to a lower the rotary cutter in the act of cutting the cigarette rod, or more accurately speaking, the rotary cutter is given a quick down ward movement at the time the cigarette rod is being cut and while the'knife is receding from the cut rod, but during all the rest of the upward movement and the corresponding downward movement, a slower movement is imparted. And likewise, the eccentricallyarranged shaft 48, connected by the link 58 with the shaft 41, causes an irregular movement to be given to the sleeve and'its cutter shaft 71. In other words, the cutter shaft 71 with its sleeve 70' is given an accelerated or more rapid movement when it is moving the cutter in the di rection opposite to the movement of the cigarette rod, while a retarded or slower movement is given to the sleeve 7 0 and shaft 71 during the time the knife is traveling with the cigarette rod and the rod is being out. By this means, I am enabled to provide a cutting mechanism wherein the rotary cutter, its ledger plate and the cigarette rod are traveling exactly at uniform speed with the cigarette rod and by which a quick dipping movement is given to the rotary cutter at the time the cigarette rod is being cut, and during this movement the ledger plate, while moving at the same speed as the cigarette rod, is traveling at a relatively slow speed compared with its movement during the time the cutter is not performing its cutting operation. As soon as the cutter recedes from the cut rod its further upward movement and most of its downward movement is retarded by the eccentric connection, while on the return movement of the ledgerplate, the sleeve-70 and the cutter shaft 71 is accelerated. The result of the two movements just described is a peculiar movement given to the cutter shaft and its cutter. Owing to the fact that the frame 66 is driven by the cranks 60 and 61, any given point on the said frame 66 will be given a complete rotary movement. But during this rotary movement to which each part of the frame 66 and its bearings 68 and 69 is subjected, it must be remembered that the cutter shaft and its cutter are being moved longitudinally in said frame 66 and its bearings, and it must also be remembered that the rotary movement given to the frame '66 is accelerated, at one part of the circular movement, and that the longitudinal movementgiven to the cutter shaft is also accelerated during one part of its movement. And it must also be remembered that as the eccentricity of the central shafts is opposite to the eccentricityof the outside. 'shafts the accelerated movement is given to Hence,

the movement given to the rotary cutter.

From this figure it will be seen that the movement is substantially triangular with rounded corners; The actual cutting is done in that part of the triangle represented below the dotted line a-a and it is during this part of the downward and upward move cutting is actually taking place, the cutter shaft and its cutter and the ledger plate are traveling at the retarded speed simultaneously with the movement of-the cigarette rod, while duringthat part of the movement represented by the triangle above the line a-a, a retarded movement is given to v the .up and down motion of the cutter. It is as the rotary cutter is reduced in diameter byits being periodically sharpened,

Instead ofthe cross-heads connected to the various eccentrically arranged shafts, I may use a pair of cranks as illustratedat 140 and 14:11 1]. Figs. 7 and 8'connected by a pivoted 7 link 142, or I may usetwo disks 143 and 144 .by apivoted link so that the cutter will be given a quick dipping movement, but in the connected by a pivoted link 145. I regardv each of these constructions, shown in Figs. 7 8 and 9, as the equivalent of the construc: tion shown in the other figures of my 7 drawing.

7 In a companion application I have shown and broadly claimed a cutter having 'two shafts eccentrically arranged and connected present application this same mechanism is claimed in combination with asecond eccenat the same time anotherjshaft is arranged to impart a movement'to the cutter to and passing through the same. V r

- tricallyarranged shaft forgiving a 'backwardand. forward movement ltothe cutter simultaneously with its quickf downward movement. I

Wherever inthe following, claimsI have referred to two shafts eccentrically arg .7 ranged I do not necessarily limitinyself' to" an arrangement where there aretwo sets of" shafts 40 and 42 and a third shaft 43 but in; tend the word two asbroa'denough to cover two. shafts as well "as two or -more,'the priing the cutter shaft and ledger plate a-move ment parallel with I the cigarette rod while from the ledger plate and the, cigarette rod In illustrating my invention I have shown one embodiment thereof, but do not inte'nd my claims to be limited to the construction shown as I desire-to claim broadly'a cut .t'er combined with eccentrically arranged shafts whereby one shaftis employed to give the cutter shaft a longitudinal movement.

while another eccen'trically arranged shaft, is employedto give anup andvdown move ment to the cutter, whereby thelpeculiar ef-V feet hereinbefore referredi to is obtained,
